Given following data in the participants collection

{

"_id" : 5,

"quizzes" : [

{ "wk": 1, "score" : 10 },

{ "wk": 2, "score" : 8 },

{ "wk": 3, "score" : 5 },

{ "wk": 4, "score" : 6 }

]

}

What is the output produced by the following mongoDB operation?

db.participants.updateOne(

{ _id: 5 },

{

$push: {

quizzes: {

$each: [ { wk: 5, score: 8 }, { wk: 6, score: 7 }, { wk: 7, score: 6 } ],

$sort: { score: -1 },

$slice: 3

}

}

}
